Easy way to switch between apps?Support

My first post from my brand new Fascinate! So if my spelling is off, I can blame fat fingers on the keyboard.

Is the there an easy way to switch between open apps? I'm listening to Pandora while playing a game, and I've got the browser open to read insructions. Pandora showed on the top bar, and I found how to pull that down to get back to it.

But to go from any screen back to the game or the broswer, I had to go to the home screen, then the apps menu, then select the app. Is there a way to just go right from one to another?

(And is there any way to move forward or backward in text one charactet at a time?!?)
